Effect of Different Artificial Vegetation on Soil and Water Loss and Soil Moisture in Loess Hilly Area in Northern Shanxi Province
Based on the runoff plots located in Yanggao county,Shanxi province,effects of different vegetation on soil and water loss and soil moisture in Loess hilly area in north Shanxi province were investigated.The results showed,compared with bare land,Caragana,Hippophae and Pinus tabulaeform could control soil and water losses effectively,with the runoff reduction rate of 84.8%～95.9% and sediment reduction rate of 95.2%～99.7%;wasteland and Alfalfa could control soil and water losses effectively from the third and fourth years,with the runoff reduction rate of 82.8% and 91.2%,and the sediment reduction rate of 97.0% and 98.0% respectively in the fourth years;coefficients of variation of soil moisture were ranged from 7.0%～19.1% in different vegetation plots from April to September,and that of Pinus tabulaeform plot was the highest,Hippophae,Alfalfa and Caragana were following,and wasteland and bare land were lower;deficiency rates of soil water were ranged from 23.98%～52.66%,that were in the order CaraganaAlfalfaPinus tabulaeformHippophaewastelandbare land,implying vegetation could increase the variation and deficiency of soil moisture.
